1. Vacuum under the cushions of your sofas and stuffed chairs. Lots of things, big and small, like to hang out in there.
2. Go through your closet and take out those clothes you haven't worn in forever for Goodwill. Marie Kondo's criterion: if it doesn't give you joy, toss.
3. Put your winter hats and gloves and boots back in the closet and take out the spring stuff if you have a bin for these things.
4. Clean the glass on the framed pictures you have hanging on the wall..
